Abstract
The invention relates to an apparatus for collecting and measuring volume of liquids. The apparatus comprises a vessel (1) having a liquid inlet (2) and a liquid outlet (11). The vessel comprises a guiding member (4) defining a vertical movement guidance for a float (5) adapted to be disposed at a level equal to the surface of a liquid (6) in the vessel. A light source assembly (7) provided above the float (5) emits a light beam towards a surface of said float, which surface being diffuse reflective. Sensing means (8, 15) senses diffused light reflected from said float surface, and processing means (18) receives and processes input from said sensing means (8, 15) based on the diffused reflected light so as to calculate the level position of the float (5) and thereby the volume of liquid (6) present in the vessel (1).
